This invention relates to that class of window glass guides which are formed of metal bent in channel, or U-form and are generally employed in closed body automobiles. Y

The metal channels employed in the less expensive grades of automobiles are usually formed of steel or other comparatively low cost metal, but in those grades in which the best, or most expensive materials are demanded these metal channels'are usually formed of non-corrodible metal, which is much more expensive than that which is more commonly used, as for example, stainless steel, silver," or chromium plated stock, so that the exposed portions of the channel will constantly have an attractive appearance. As these metal channels are almost invariably secured in a groove within the window casing, only the edges of the sides thereof are visible, so that no advantage is derived from having the unexposed portion of the channel formed of expensive material.

The primary object of my invention is to provide a form of metal window glass channel which will, when installed, have all the advantages of such a device when constructed from the more expensive non-corrodible metals, but ,which may be produced at an expense which will be but slightly greater than that of the less expensive construction more generally employed.

I accomplish this and other objects of my invention by providing the side edges ci an ordinary metal channel with a finishing bead or molding of a more expensive or non-corrodible metal, so that its outward appearance will be the same as if the channel were constructed completely of the latter metal, and by providing means whereby the finishing bead of the higher grade metal may be securely attached to the side edges of the channel formed of metal of the lower grade.

For a more complete disclosure of the invention reference is made to the following speciiication, in connection with the accompanying drawing, in which:-

-As shown in the drawing, a main channel portion a of common U-form is provided, which is formed from thin, comparatively inexpensive metal, and according to the invention, as shown in Figs. 1, 2 and 3, a series of slits a are cut in the edge portion of each side at suitable intervals, as shown in Fig. 5, said slits being extended inward from the edges for a suiiicient portion of the height, or width of the sides, thus separating each edge portion into a series of tongues a2. As shown in Figs.'2 and 3, alternate tongues of a series are bent inwardly of the channel and the others of the series are bent outwardly in opposite relation to the plane of the side from which they are formed.

The extent to which these tongues are bent from the plane'v of the side and the 4particular forminto which they are bent may be varied indeiinitely. As shown in Fig. 1 the tongues are rolled outward and'inward into an approximately semi-cylindrical formation, so that the adjacent tongues together form a transversely enlarged, or thickened, approximately cylindrical edge, which is divided by the plane of 'the side. A bead, or small molding b is provided which consists of 85 a strip of metal bent into partly tubular, or U- form, the metal of which it is constructed having an ornamental finish which is preferably rust proof, or proof against discolorations, so that it will always present an ornamental appearance. The formation of the bead b may be somewhat varied, but in all instances is similar to the construction shown in Fig. 4, and is adapted to be lplaced over the transversely enlarged edge portion of each side of the channel by passing the edge portion through the slot formed between the edges of the strip forming the bead and forcingA the edges into clamping engagement with the inner and outer surfaces of the side, or the enlarged edge portion thereof, to which it is attached.

As shown in Fig. 1, the head b is formed cylindrically, so that its inner surface corresponds to the outer surface of the approximately cylindrical enlargement of the sides. If the bead is of non-resilient metal it may be placed in position on the enlarged edge portion and clamped together against the sides thereof. If it is formed of somewhat resilient metal, it may be sprung open sufficiently to permit it .to be placed in position and spring into clamping engagement. The bead may also bc mounted on the edge by a telescoping operation, but as these channels are usually made in longstrips, and a subsequent clamping operation would be necessary, such a method is considered impractical.

As shown in Fig. 1, the rolled over tongues a-I may also be employed for the purpose of holding a covering c for a cushioning lining e, by clamping the covering between the edge of the tongues and the inner side of the channel. ,Also ythe outwardly bent tongues may be employed to hold felt strips d in position between the outer sides of the channel and the sides of the casing groove in which it is located, the felt strips being, if it is desired, also adhesively connected to the sides of the channel grooves.

In the form of the invention shown in Fig. 6, the alternate tongues a.3 are shown as bent inwardly towards the base of the channel at the outer and inner sides of the channel side and extended in divergent relation. Said tongues are also held in clamping engagement with the covering c' and felt strip d and the bead b' is designed to be pressed on over the enlargement formed by the tongues and to be resiliently engaged therewith, and also with the covering felt strip.

In the form of Fig. 7 the alternate tongues a4 are shown as bent oppositely at right angles to the sides and then outwardly from the channel bottom and convergently in curved formation, to provide a seat for the bead b2, which is similar to the form previously described and, when in position has its edge portions clamped against the inner portions of the tongues. The edges of the bead are also engaged with the lining covering c2 and felt strip d2, as in Fig. 6.

In Fig. 9 the alternate tongues a5 are shown as bent oppositely at right angles to the sides, to form the enlarged edge, and, in this instance, a lining covering c3 is shown as extended over the top of the edge and downward on the outer surface of the side and as clamped between the opposite portions of the bead b3, which is "shown in this instance, as having its outer side portion extended for a distance down on the outer side of the channel, to give a iinish to the side, and as turned out from the side, at the inner side, to prevent cutting the covering. p

In Fig. 10, the construction shown is similar to that of Fig. 9, except that only the alternate tongues a6 are bent out of the plane of the sides, said tongues being bent inwardly of the channel at approximately right angles, and the other tongues being left in the plane of the side. In this instance the form of the bead b4 will be correspondingly changed, but will be similar to that of Fig. 9.

In the constructions of Figs. 8 and 11, instead of slitting the edge portions of the sides to form tongues, from which the transversely enlarged edge-portion is to be formed, a series of tongues a.l in Fig. 8, and a in Fig. 11, are struck out from the sides and bent inwardly of the channel, by cuttinga series of longitudinal slits in each side and transverse slits therein which extend from the ends of the longitudinal slits, towards the edge, but terminate at a distance therefrom, thereby forming a series of apertures fin the sides, as shown in Fig. 12. The constructions of Figs. 8 and 1l are practically the same, except that in Fig. 8 the edge portion of the side is left in the plane of the side and the tongue is extended towards the channel bottom at a slight curvature and in Fig. 11 the edge portion is bent outward from the channel and the tongue is curved outward fromthe bottom.n The beads b5 and l)6 are-also formed somewhat differently to conform to the edge and tongue portions with which they are engaged, but the construction and method of application is substantially the same as previously described. In this instance also the channel is lined with a felt cushion e', e2, which is held in the channel by the tongues and protrudes through the apertures f, so that the felt is engaged with the sides of the casing groove in which the channel is located.

In all of the constructions above described the bead or molding having a finished surface which gives the channel an ornamental appearance is securely attached.

It will be understood that it is immaterial to the invention, so far as the matter of the generic means employed for securing the bead in position is concerned, whether the engagement of the edge portions of the'bead with the sides is direct or through intervening material which it is desired to secure in position in or on the side of the channel.
